net/sched: cls_flower: Add support for matching on ct_state reply flag
This patchset adds software match support and offload of flower
match ct_state reply flag (+/-rpl).
The first patch adds the definition for the flag and match to flower.
Second patch gives the direction of the connection to the offloading
drivers via ct_metadata flow offload action.
The last patch does offload of this new ct_state by using the supplied
connection's direction.

Pointers to receive-buffer packets sent by Hyper-V are used within the
guest VM. Hyper-V can send packets with erroneous values or modify
packet fields after they are processed by the guest. To defend against
these scenarios, copy (sections of) the incoming packet after validating
their length and offset fields in netvsc_filter_receive(). In this way,
the packet can no longer be modified by the host.

We currently just percolate the return value from analyze_instr()
to the caller of emulate_step(), especially if it is a -1.
For one particular case (opcode = 4) for instructions that aren't
currently emulated, we are returning 'should not be single-stepped'
while we should have returned 0 which says 'did not emulate, may
have to single-step'.

properties even on smaller (2 socket) POWER systems. This selects them

In commit 8150a153c0 ("powerpc/64s: Use early_mmu_has_feature() in
set_kuap()") we switched the KUAP code to use early_mmu_has_feature(),
to avoid a bug where we called set_kuap() before feature patching had
been done, leading to recursion and crashes.
That path, which called probe_kernel_read() from printk(), has since
been removed, see commit 2ac5a3bf70 ("vsprintf: Do not break early
boot with probing addresses").
Additionally probe_kernel_read() no longer invokes any KUAP routines,
since commit fe557319aa ("maccess: rename probe_kernel_{read,write}
to copy_{from,to}_kernel_nofault") and c331652534 ("powerpc: use
non-set_fs based maccess routines").
So it should now be safe to use mmu_has_feature() in the KUAP
routines, because we shouldn't invoke them prior to feature patching.
This is essentially a revert of commit 8150a153c0 ("powerpc/64s: Use
early_mmu_has_feature() in set_kuap()"), but we've since added a
second usage of early_mmu_has_feature() in get_kuap(), so we convert
that to use mmu_has_feature() as well.

When MSI_FLAG_ACTIVATE_EARLY is set (which is the case for PCI),
__msi_domain_alloc_irqs() performs the activation of the interrupt (which
in the case of PCI results in the endpoint being programmed) as soon as the
interrupt is allocated.
But it appears that this is only done for the first vector, introducing an
inconsistent behaviour for PCI Multi-MSI.
Fix it by iterating over the number of vectors allocated to each MSI
descriptor. This is easily achieved by introducing a new
"for_each_msi_vector" iterator, together with a tiny bit of refactoring.

Our system encountered a re-init error when re-registering same kretprobe,
where the kretprobe_instance in rp->free_instances is illegally accessed
after re-init.
Implementation to avoid re-registration has been introduced for kprobe
before, but lags for register_kretprobe(). We must check if kprobe has
been re-registered before re-initializing kretprobe, otherwise it will
destroy the data struct of kretprobe registered, which can lead to memory
leak, system crash, also some unexpected behaviors.
We use check_kprobe_rereg() to check if kprobe has been re-registered
before running register_kretprobe()'s body, for giving a warning message
and terminate registration process.
